At first glance there doesn't seem to be a difference between surfaces done with the RS2 vs. an RO150 or ETS (EC) 150 -- they both feel smooth to the touch and look even when looking at them overhead.  But bring your eye to the level of the sanded surface and look down the edge, and you will be able to see just how much of a difference the RS2 makes. 

Just curious Edward, how the swirl patterns compare to each other. Can you see an actual difference in surface quality?

The nice thing is the RS2 has a 33% greater pad area than a 150 mm ETS EC sander and there's only a .5 mm difference in stroke between them.

I use my RS2 to do the yearly refinishing of a teak table outside.

Its one sander I haven't tried but I also have never had the issue of dishing you mention. On larger surfaces like table tops my pieces are typically all planed to within a couple of thousands of an inch then run through a wide belt using 100P before glue up. I then domino the pieces for alignment. The final sanding is then done with an ETS 150 EC with the hard blue pad on 6 with low suction. Final touch is hand sanding with the grain direction. Using the regular pad and an improper method will compromise a flat surface.

Eliminating 90 percent of the opportunity to mess up the surface with small powered sanders running coarse grits is a good process.

@Cheese I've never gone and looked with a microscope, but surface quality appears to be the same in my opinion.  I only go up to 220 grit on the RS2, so I'm not sure if you would realize any advantages at higher grits.  I've never been dissatisfied though with how the 150/3 performs above 220.  The only advantage you might get with the RS2 is on swirls produced by tears to the abrasive.  Occasionally the ROS will catch a corner or an edge and fray the edges of the paper or nick one of the holes, which will then show up on the material surface.  That's a lot harder to do with the 2mm orbital stroke of the RS2.
